Suddenly, No. 1-ranked Corona High’s baseball team isn’t looking so invincible.

The Panthers have been struggling to score runs, and Corona Santiago took advantage with a 1-0 win on Thursday in a Big VIII League game.

Cooper Berger threw six scoreless innings. Santiago (14-7, 5-4) scored the game’s only run in the top of seventh on an error. In the bottom of the seventh, Corona (19-2, 9-1), which was limited to one hit in the game, loaded the bases with one out against freshman pitcher Striker Pence, but then stranded the runners after consecutive pop flies.

Seth Hernandez struck out eight in three innings for Corona and Ethin Bingaman struck out nine in four innings but took the loss.
